I never leave our base for the bush without one, winter or summer. In the winter I always carry a portable in the squirrel cheek.I don;t shut down in the bush below -20c, unless a chip light or some such forces me to. Try getting a start at -30c/-40c while it has been sitting for 10mins while you have a looksee, ya might, ya might not.......I don't intend sitting on the ice/in the bush for the night at -20 let alone -40, unless there is no option, bin there seen it,done it, got the t-shirt thank you very much.....
not fun...and definately not because of a weak/flat battery.
Funny old winter here, bird towing in Quebec last weekend, -30c with -45 wind chill....
Now moving drills 80nm to the west, today +10c go figure. Still carried my APU though....
Winter not over yet I fear, although I live in hope.....roll on bug season, can't wait.....not
